Salutations. Im having problems with an oil change on an 07 wr450. Draining the oil was easy, but getting the oil inbetween the min / max points on the dip stick seems impossible. One minute im nearly there at max, so i add a tiny amount of oil, fire it up for ten seconds re-check and oil has vanished (below min) or appeared (above max). I've litteraly spent all afternoon trying to set the right oil level. What am i doing wrong? Im using the kick stand not a proper stand. For sure this is embarrasing lol. All testing was done with warm oil. The filter has not been touched. One thing was noted, was that when there was to much oil in the engine, the cylinder head was abolutely quite. Spark plug: Do i need to remove bodywork/fuel tank to remove the spark plug? How do I connect the supplied plug puller to my torque wrench or do I need another plug puller? The coolant weep hole is leaking. I guess the seals need replacing. Are any specialist tools required to bleed the coolant system or it a matter of filling the radiator right to the top? Thank god this site exists. Thanks guys.
